Adjustable featherboard with Anti-kickback device

Abstract

An adjustable featherboard device includes an elongated bar having a shape and size that is suitable for engaging the miter slot of a table saw. An elongated featherboard body is pivotally secured onto the top of the bar and rotates 360 degrees along a horizontal plane. The featherboard body includes a first end for imparting a lateral force onto a side section of a piece of stock located on the table saw. An anti-kickback member is pivotally secured along one side of the featherboard body adjacent to the first end. The anti-kickback member includes a cam body having a notch section and a protruding section for engaging a top surface of the piece of stock.

Description

TECHNICAL FIELD[0001]The present invention relates generally to table saw accessories, and more particularly to an adjustable featherboard with an anti-kickback device for guiding stock along a saw to be cut.BACKGROUND[0002]The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.[0003]A table saw typically includes a motor-driven circular saw blade centrally mounted beneath a generally horizontal saw table having a blade slot through which the saw blade protrudes. A rip fence comprising an elongated raised bar is slidingly connected to the table, and is oriented parallel with the saw blade. An elongated miter slot is formed in the surface of the table on the opposite side of the blade slot, and is also oriented in a parallel direction to the saw blade. The miter slot typically extends the length of the saw table and includes a shape and size that is suitable for receiving accessories such as a miter gaug...

AI Technical Summary

Benefits of technology

The present invention is about an adjustable featherboard with an anti-kickback device. It includes an elongated bar that can be placed in a table saw's miter slot and a featherboard body that can move in multiple directions. The featherboard has a first end that applies pressure to a piece of wood on the table saw. An anti-kickback member is also included, which pivots on the featherboard and has a cam body with a notch and protruding section that engages the wood surface. The technical effects of this invention include improved accuracy and stability when making table saw cuts, reduced kickback, and improved user safety.

Problems solved by technology

Although current featherboard designs work well to impart a constant pushing force against stock such as wood, for example, that has perfectly straight side edges, they do not work well with materials that do not have straight side edges.

Indeed, in such situations it is not uncommon for the distal end of the featherboard to lose contact with the side of the material.

Such a requirement often leads users to simply continue the cutting process without the aid of the featherboard.

Unfortunately, when this situation occurs, the above described featherboards do nothing to prevent a dangerous kickback situation.

As such, it is not possible to utilize the entire space between the slot and the cutting blade, thereby reducing the shape and size of material(s) that can be used with the same.
